Only one Ethernet connector for everything

Hello,

I have some boxes and a switch. Each box has only one Ethernet connector.

Is it possible to make a box with only one Ethernet connector a gateway?

All the local boxes are connected to the hub and the hub is connected with
my cable modem (with one WAN IP only).

Can I set up one of the boxes as a router / gateway to the Internet for the
other boxes on the hub through only one Ethernet patch cable to the hub
acting as Internet gateway AND router?

I mean - Can it be done?

Many Thanks

Guy

Google for "router on a stick" or "one armed router"

Ahhh - keywords. Thanks, Roy. They're bearing fruit.

Yes, but it is not real a nice way (hub and external traffic on this
device).
You could setup different vlan's on this nic.

Yes. he would have then a vlan with your LAN's IP and a second vlan with
your external IP.

You can buy yourself another ethernet card for £5 (probably $10US) so
why not just get one and stop struggling!

Thank you all for your encouragement. With an Ethernet card it would be as
simple (almost) as plug n' pray but my machines have no PCI slots. They are
Dell SX270's I found in a skip. I need the 'one armed router' or 'router on
a stick' solution.

Chucked because of a motherboard failure. I have put some new caps on the
mobo and they run fine! 8-)
